Is this even possible?

says this (under the "free" section):
Approx. ten gallons used motor oil

The person who was going to pick this up two weeks ago never showed up, so it's up for grabs one more time. In ten one gallon milk jugs. Please; SERIOUS INQUIRIES ONLY!!! mkepp


Wow, really? You have used motor oil? For free? Why, I would think people would pay hundreds of dollars for that. I mean, it has so many uses. You can...illegally dispose of it in your back yard, pay to dispose of it at an oil changing place, or...well, that about covers it. Hard to believe this one is still available. But call now, operators are standing by.
